If it falls, hang the chain on the pinion with the thumb, forefinger and middle finger of the right hand (that is, a tooth is stuck in a hole).

After fixing the back, start the front of the chain. Or use the thumb, index finger and middle finger of the right hand to clip the hole of the lower chain into the lower tooth. The left hand began to slowly reverse the chain, and the chain card stuck between the teeth moved backward, and the right hand leaned against the chain. In this way, in the process of chain inversion,

Many holes can be stuck in teeth, about half a circle, that is, 3-4 teeth are stuck in the air. The right hand can slowly leave, and the left hand can continue to reverse the chain. It may get stuck halfway. As long as it's not caused by overlapping chains, don't worry. Just pour it hard and the chain will go up. You can go to the garage to see more, and the actual operation is not difficult.

The crisis of old and damaged chains;

If the chain is neglected for a long time, it should be cleaned and oiled regularly, because the chain will get stuck in a lot of dirt in the environment after repeated use, making the chain useless.

You can't easily change your own upper and lower chains by shifting gears, which directly leads to unsmooth riding and a sense of Kaka.

The chain is suddenly broken and dropped during riding;

This is definitely what athletes and riders are most afraid of when riding.

Chain dropping may be easy to solve, but it also directly indicates that your chain is quite old, easy to loosen and lose its original elasticity, which will weaken the effect and significance of speed change.

Broken chain is an unexpected situation that is difficult to solve. You must always carry repair tools, reassemble the chain halfway and restore it to its original state.

It is suggested that cyclists knock off the broken chain first, and connect the two ends temporarily with quick buckles before continuing to ride for a short distance;

Of course, the best advice is to use an electronic card gauge or a simple card gauge to measure eight eyes, and carefully check whether your chain exceeds the elongation to ensure the life of the chain.

Bicycle chain cleaning, the standard of chain cleaning:

When you find that the speed change effect is not good when riding, it will be loose or uncomfortable, and even make noise when running, which reminds you that the chain needs to be sorted out urgently.

Generally speaking, the use of chains depends on the rider. Even if your riding environment is not too muddy, you should maintain it at least once a month, which will not only increase the sliding force of the variable speed chain, but also align the connection points of the upper and lower chains more accurately to avoid falling off the chain.

Bicycle chain washer:

First, open the lid, put in diesel or gasoline (diesel is recommended), then put in the chain, cover the lid and turn the chain until it is clean.

Pour out the diesel oil, add a little detergent and water, clean the chain again, and dry the chain with a dry cloth after cleaning. At this time, the chain is as clean as a necklace.

Next, don't forget the most important step. Be sure to oil the chain, or it will rust in a few days.

Proper maintenance and cleaning process of bicycle chain;

Using the correct maintenance and cleaning process can effectively increase the life of the chain; Instead of taking your bike to specialty store, you should learn DIY technology, which is convenient for you to handle it carefully at home, not only saving a lot of maintenance costs, but also being close to your bike.

Step 1: spread a newspaper or rag on the work floor to receive excess cleaning liquid that may drip from the chain during cleaning.

Step 2: put the bicycle on the maintenance rack, change the toothed plate to the middle plate or small plate, and rotate the flying wheel to the middle gear. Adjust the bicycle so that the lower layer of the chain is as parallel as possible to the ground.

Step 3: Wipe off some dirt, dirt and dirt on the chain with a brush or rag.

Step 4: Fill the washing machine with washing liquid.

Step 5: Place the chain washer at the bottom of the lower chain, between the toothed plate and the flywheel, and assemble the chain washer.

Step 6: Hold the handle tightly and slowly turn the crank counterclockwise. After a few turns, the chain is clean. If necessary, add new cleaning solution and continue cleaning until the chain is clean. Hold the handle with your left hand, turn the crank with your right hand, and the chain can rotate smoothly only when both hands are balanced. It may not be easy to grasp the strength at first, but it won't move, or the chain will be pulled down from the tooth plate, and you will get used to it. When cleaning, you can turn it a few times and try to clean the gap.

Step 7: Wipe off all the cleaning liquid on the chain with a rag and try to dry it. Change the speed back and forth, and then wipe off the residual cleaning liquid at the tooth plate and flywheel. After wiping, put it in the sun to dry or air dry, and the chain can not be oiled until it is completely dry.

Step 8: Wipe off the scattered pollutants immediately, and dispose of the cleaning solution and dirty rags. When finished, rinse the washer with water and air dry.

What oil should be applied to bicycle chain and its oiling skills;

Step 1: There must be oil pollution between each piece of metal that constitutes the chain. When refueling, drop oil one by one on both sides of the chain pin (this is where the chain really needs lubrication). If the chain has a 108 pin, drop oil at 2 16.

When you use an oil bottle, if you turn it upside down, the oil will drip. The disadvantage is that the oil quantity is not easy to control. You can use a syringe for better effect. Because there are many places to refuel,

You can mark the chain with an oil pen first, and then oil it from the mark. When you touch the mark, it means it is finished. Use a syringe to drop oil on both sides of the chain, 1, 2 drops at a time.

Step 2: After putting it on, let it stand for a few minutes to let the oil soak the whole chain.

Step 3: The oil left outside the chain will only stick to dust. Wrap the chain with a dry rag, turn the crank and wipe off the excess oil.

Step 4: If there is a lot of oil on the toothed plate and flywheel, change the speed back and forth to separate the chain from the original toothed plate and flywheel, and dry the oil on the toothed plate and flywheel with a rag. These oils have no other function than sticking ash.

Step 5: After every ordinary ride, keep it clean with a rag, and then clean and oil it later. Riding in muddy places, the oil on the chain will soon disappear. At this time, the chain is heavily worn and loud, so it needs to be replenished in time.

Warm reminder: Many riders are used to soaking the chain in detergent, then picking it up for deep cleaning after a while, and even using a highly corrosive herbicide to remove rust, which will cause great damage to the chain.

Detergent goes too deep into the details of the chain by soaking, making it too clean, eroding the surface of the chain, making the overall texture of the chain vulnerable to external forces, very fragile and more likely to break.
